Development and Deployment of Involute Splines Cold Forming Process for Gear Manufacturing
A dynamic simulation model for cold forming of involute splines through a rolling process is presented. The model identifies a unique rolling methodology which consists of various phenomenon to illustrate the forming process in detail. Mass produced involute splines on four loose gears in a six …

Evaluation of lubricants for cold forming of steels by double-cup extrusion tests
… shear factor between the workpiece and the forming tool in cold metal forming processes. The test was adapted to be used under production conditions and applied to characterize and compare the lubrication properties of different types of lubricants and coatings.;It was found to be a useful …

Thermomechanical modelling of powder compaction and sintering
… elastic-visco-plastic thermomechanical model for cold forming of ceramic powders and subsequent sintering is introduced and based on micromechanical modelling of the compaction process of granulates. Micromechanics is shown to yield an upper-bound estimate to the compaction curve of a granular …

Plastic buckling in gas transmission line-pipes, cold formed from thermo-mechanically-controlled rolling of low-allow steel plates
… and anisotropy in the pipes. The plates are then cold-formed into pipes, which introduces further anisotropy and residual stresses in the pipe. In the current work, effects of various steps of the pipe manufacturing process, such as rolling, cold forming, etc., on residual stress, hardening …

Development of rate-dependent thermoplastic constitutive models for numerical analysis of ceramics at high-temperature
… first model is elastic-plastic and addresses the cold compaction of ceramic powders, combining nonlinear elasticity, elasto-plastic coupling and increase of cohesion. - The second model is thermal-viscous-elastic-plastic and is specifically tailored to describe the thermo-mechanical behavior of …

The effects of corner radii on the local buckling of cold-formed sections
… produce structural members include hot rolling, forming and welding hollow section (HSS) and welding plates to form I's (WWF). Another method, which is less widely known but is growing in acceptance, is cold-forming from steel sheet or strip using roll-forming machines, press and bending brakes, …
